Theil whom t may concern i Be it known lthat I, GIDEON PILLOW BROWN, a citizen of the United States of "America, and resident of Chicago, Cook county, Illinois, have'invented a certain new and useful Improvement in Tater-Tube Scot-Blowers, of which the ifollowing is a specification.' A My invention relates to soot blowerslfor waitery tube boilers.`

It relates more particularly to blowers for `this purpose that have a set of nozzles arm ranged. to extend through 'the side of the furnaoje wall, and whichy are mounted to,

swing om side to side; These nozzles are arranged in line with the spaces between the and when used in conjunction with a boiler atlng in horizontal planes, swing across the tubes, which 1s objectionable.

lthe tubes,

tubes, so that the jets do not impinge directly against the side of the tubes, but simply pass in between the tubes. This mode of operation is all right for a boiler in which the tubes are horizontal, as in such case the back and forth swing of the nozzles does not cause the jets to cut across the tubes. ln boilers, however, in which the tubes are inclined, as is often the case, the nozzles, operobliquely To it has been found, the always blow between and never cut across the same. The object of my invention is,therefore, to provide an arrangement whereby, the noz zles of the blower, when disposed in position to swing vabout a vetrical. axis, or when disposed one above the other in vertical series,

get the best results, jets or blasts should in which the tubes are inclined, will keep the jets or blasts moving between the tubes, by causing the nozzles to follow the direction of the tube, thus preventing the same from cutting across the tubes, orat least greatly reducing the tendency in that direction, during the sweep of the nozzles from side to side, and in conjunction' with a vertical supply pipe to which the nozzles are suitably connected. "lt 'is also anl object .to providean limproved arrangement for withdrawing the nozzles from the furnace after the soot has been blownfrom the tubes.

It is also an object, of course, to provide an improved arrangement* whereby the nozzles may swing in planes parallel with the inclined tubes, in conjunction with a furnace having a verticalopening in the side wall thereof,- an opening of this hind being more Specication of Letters Patent.

brick wall, for in a wall of this kind an'inclined opening has been found to be undesirable.

To these and other useful ends my invention relates to matters hereinafter set forth and claimed;

In the accompanying drawings Figure 1 is a Side elevation of a soot blower for water tube |boilers, showing one side of the furnace, and a number of furnace to blow the soot lolf from the tubes. Fig.` 2 isa front elevation of the structure shown in Fig. l. Fig.8 is .a horizontal sec- Fig. l. Fig. l is an enthe tubes, in section, vand showing the nozzles pushed into the connection that permits the nozzle to move up Aand down and alsov swing sidewise about avertical axis. Fig. 5 is an enlarged section on line 5-5 in Fig. 4.

As thus illustrated, the water tubes A are inclined and arranged'in the usual and wellknown manner. The wall or side B of the furnace hasan opening C in which the plate I) is disposed in a vertical position. The

openings d in this plate are covered by thev sliding coverplatezd, whih'latter has small 'openings d2' for the nozzles E that are mounted on the iverticall pipe e. rlhe springsc arearranged on thenozzles between the pipe e and the plate df to keepthe latter pressed tightly against the plate D. Thetvertical ysupply pipe or header F has its upper end connected with the lower end of the pipe e by an elbow coupling-f having a handle fto swingthe pipe c from side to side about a vertical axis coincident with the -pipe F. This pipe F is supported by pins f2 that engage in cam slots f3 in the sides of the nozzle base f4. 4These cam slots cause thepipe F to move up and down when oscillated or turned back and forth by the handle f. ln this way, and by moving the nozzles up anddown while they 'move from side to side, they are caused to follow the slant' or incline of the water tubes; so that the jets or blasts never cut across the tubes,

or at least have less tendency to doso than in arrangements where the nozzles swing in horizontal planes. slots 7' is such that the up and down motion is just sufficient to keep lthe nozzles always pointing betweenI the tubes A.' Thus the side sweep of the jets or blasts does not, at least'not in the way they would. `if operated in horizontal planes, bring them against ythe The angle of the camV fso tubes, even :in a boiler in which the tubes are inclined.

The airor steam for blowing is supplied from a pipe G and through the telescoping connection g to the swivel connection g. The latter is so constructed that the rise and fall and the oscillation of the pipe F does not cut 0H the pressure. The connection g permits theblower to be moved in and out, so that when theblowing'operation is finished the nozzles can be withdrawn from the chamber. For this purpose the base f" is mounted on tracks f, and a hand lever II is connected by a link it with the swivel joint g', whereby the blower can be pushed into position and then pulled out. The slots f can have steps f to enable the operator to raise and lower the blower step by step, thus making the operation easy and convenient. A lever I may be provided for assisting in the control of the movement ot' the pipe e, if such is necessary.

Thus I provide a soot blower that can be operated' in. connection with a boiler in which the water tubes are inclined. The blower will work in a vertical position, and will always blow between the tubes, or at least have a greater tendency to do so, fully as well as in a boiler where the tubes a're horizontal. i

Obviously, the provisions or mechanism for causing the nozzles to follow the direction of the tubes may be of any suitable, known or approved character, and I do not, therefore, limit myself to the exact con struction shown and described. My invention contemplates, broadly, a set of nozzles arranged one above the other in vertical series, each nozzle movable in a plane parallel with the inclined water tubes but oblique to the said vertical Series arrangement of the nozzles.

My invention, it will be seen, has the great advantage that the nozzles swing in planes parallel with the water tubes, notwithstanding that the supply pipe or header is verti`- cal, whereby the latter may be disposed in the vertical opening in the side wall of the boiler, and whereby, also, the blower may be mounted for withdrawal from the boiler when not in use.

It will be seen that the nozzles E are not only so connected together and arranged and operated that they are all on a vertical line when in normal or central position between the two sides of thevertical opening iu the wall of the furnace, but are also con-y structed andarranged 1n such manner that the series of nozzles iseXactly vertical Curing the operation of the blower, and for all positions of the nozzles. In other Words, the nozzles are all arrangerl one above the other along a common vertical line, and

this line is always vertical, regardless of' the position of the nozzles. Thus, when the nozzles are swung to one side, they v ill all encounter the side edge of the verticall opening at the same time, so that they all have the same degree of movement to either side of the center position. Also, the nozzles all move at the same speed, during the operation of the blower, because they are all of the saine length and move about a co1nmon axis. It will also be seen that my invention avoids the necessity of making inclined openings in the side wall of the boiler. As is well known, an inclined opening is objectionable, especially when the wall is made of brick,- and for this reason it has become desirable to ilse vertical openings. Thus, I provide a blower in which the nozzles will follow the general direction of the inclined water tubes, and which can be used with a boiler setting in which the side walls are provided with vertical openings for the different passes ot the boiler, such, for example, as the ordinary and wellknown Babcock & lVilcox boiler. vThis is all accomplished, it will be seen, with a blower structure in which the upright series of nozzles is always vertical, and in which the header miy also be vertical if'such is necessary or desirable.
